/**
   File Name:          15.5.4.8-1.js
   ECMA Section:       15.5.4.8 String.prototype.split( separator )
   Description:

   Returns an Array object into which substrings of the result of converting
   this object to a string have been stored. The substrings are determined by
   searching from left to right for occurrences of the given separator; these
   occurrences are not part of any substring in the returned array, but serve
   to divide up this string value. The separator may be a string of any length.

   As a special case, if the separator is the empty string, the string is split
   up into individual characters; the length of the result array equals the
   length of the string, and each substring contains one character.

   If the separator is not supplied, then the result array contains just one
   string, which is the string.
